js获取最近7天的时间

//获取当前年月日
var now = new Date();
var year = now.getFullYear(); //得到年份
var month = now.getMonth()+1;//得到月份
var date = now.getDate();//得到日期
data = year + "年" + month + "月" + date + "日" ;

var check=[];
for (let i = 0; i < 7; i++) {
  //24 * 3600 * 1000 就是计算一天的时间  
  var date = new Date(now.getTime() + i * 24 * 3600 * 1000);
  var year = date.getFullYear();
  var month = date.getMonth() + 1;
  var day = date.getDate();
  var dt2 = new Date(now.getTime() + i * 24 * 3600 * 1000);
  var weekDay = ["周日", "周一", "周二", "周三", "周四", "周五", "周六"];
  var weekDays = ["sun", "mon", "tue", "wed", "thu", "fri", "sat"];
  // console.log(duty);
  //把七天的时间和星期添加到数组中
  check.push({
    date:year + "-" + month + "-" + day,
    day: day,
    weekday: weekDays[dt2.getDay()],
    week: weekDay[dt2.getDay()],
  });
}
// console.log(check);
t.week = check

GetTime() {
  var date = new Date();
  var base = Date.parse(date); // 转换为时间戳
  var year = date.getFullYear(); //获取当前年份
  var mon = date.getMonth() + 1; //获取当前月份
  var day = date.getDate(); //获取当前日
  var oneDay = 24 * 3600 *1000
    //var daytime = `${year}${mon >= 10 ? mon : '0' + mon}${day >= 10 ? day : '0' + day}`; //今日时间
